"Overview of Biology", the first thing He Ping saw was this book, and then, he saw "Overview of Virology", "Overview of Bacteriology", "Atlas of Microorganisms", "Theory of Virus Variation" and other books on the shelf, these books have some characteristics, such as very thick, and for example, under the title of the book, the name of the publishing department under the Shenshu Group is printed, and although He Ping also has a lot of incomprehension, but he can feel that these books are actually not very profound.

These are very basic books, and they are not internal materials, but ordinary books that can be bought in bookstores, seeing this, He Ping probably understands what is going on in this reference room, I think all the books here are similar to these books, they are not very profound, and even many of them are very basic, but they are books of the university or lower level, and these books are written and compiled by the people of the Shenshu Group, and then handed over to their own publishing department for publication and distribution.

Is it useful? He Ping frowned, whether it is useful or not, this question is really difficult for him to answer, these are basic books, not high-end technology, he himself is not a person from this world, of course he can't understand many things, but as long as people with basic education in this world can understand it, even if some of them are a little deep, college students in this world can read without obstacles, so if you look at it, it seems that these books are useless.

But now the social order of human beings has been destroyed, and the inheritance of human civilization is also in danger, although there are indeed some books and materials that have been rescued, and of course, there are data preserved by the unique storage methods of this world, but these books are even basic, even if they are the most basic literacy and arithmetic, etc., they are also tools for the inheritance of civilization, and these things are for today's human beings. Definitely not too much, and in the process of human revival, education is definitely a top priority.

After thinking about it, He Ping still put all the books here in the tower, anyway, he didn't lack storage space, since these things might be useful, then take them all away, even if he found that these things were everywhere and were not rare items, it didn't matter. It's a big deal, bring it back to the Overworld, and let those scholars who study various languages scratch their heads, it's not the language of the Overworld at all, and I don't know if those scholars have a way to decipher it.

After scavenging all the books on this floor, He Ping's confidence began to rise, there were no useful things on the more than ten floors in a row before, and now although he only found a reference room, it was only the most basic things. It's not very precious, but it's also a good sign that the upper floors of this building are not nothing, and it's not a place for the Divine Tree Group to save face. It's in stock.

However, He Ping also understands that the basement is probably the core of this building, after all, it is the safest and most confidential, and if there is any secret that the Divine Tree Group cannot leak. It must be placed in the basement, and although He Ping didn't go down when he stopped at the staircase of the hall just now, his perception had already penetrated slightly. He didn't feel the danger or anything, but he had already experienced the security in the basement, and it was definitely much stronger than the dozen or so floors he had just experienced.

But now He Ping can only continue to climb up, trying to find something useful on it, and after the data room on the sixteenth floor, He Ping has experienced four data rooms in a row, that is to say, plus the sixteenth floor, a total of five floors are data rooms, and the structure is basically the same, all have a large number of bookshelves, and a large number of books, and these books are also relatively similar, they are all popular books officially distributed through the publishing department, all of which are distributed by the publishing department under the Shenshu Group.

Although the further you go, the more esoteric the books become, of course, the reason why He Ping thinks that the more esoteric they are, is that when he reaches the twentieth floor, he can't even understand the covers of the books there, although he can understand what those words mean when they are separated, but when they are combined, they become like heavenly books, but He Ping also knows that even so, these books are not high-end materials.

After sweeping away all the books, He Ping came to the twenty-first floor with anticipation, and when he arrived here, this building could be regarded as having gone through more than half of it, and the remaining floors were estimated to be less than twenty floors, however, according to He Ping's experience from bottom to top along the way, the preciousness should gradually increase from bottom to top, of course, this is just his own values, as for what is above, He Ping doesn't know yet.

On the twenty-first floor, He Ping, who was excited, immediately lost interest, because this was the conference room floor, more than a dozen conference rooms of all sizes, and the furniture and equipment in the conference room looked very advanced, but after such a long time, there was no initial brilliance, disappointed, He Ping had no surprise, those office floors on the lower floors should be ordinary employees, and the high-level personnel here should be on the top floors for office, if you want to have a meeting, many times people in various positions have, Therefore, setting up a meeting room on the upper middle floor can not only highlight the status of the high-rise, but also save time.

After calming down, He Ping wanted to leave here, after all, there was really nothing useful in the conference room, and there was no point in staying here, but he just turned around and wanted to leave this floor and continue to walk up, when he swept his eyes and saw something unusual, in the largest conference room, there was a person sitting on the main seat, to be precise, it was a corpse that had turned into a skeleton, and what He Ping noticed was on the table in front of the skeleton, There's something that looks like a lockbox.

He Ping looked at the skeleton, and it can be seen from the torn clothes on the skeleton that this person should have a high status before his death, and he is still sitting in the main seat of the largest conference room, maybe it is the top person in charge of the branch of the Shenshu Group in this city, and he has become a skeleton instead of a zombie, which means that this person has died before the infection, He Ping saw that there was a glass vial next to the lockbox, judging from this person's posture, it is likely that he saw zombies everywhere, and he was powerless to return to the sky, Then he committed suicide, and He Ping was most interested in what was in that lockbox.
